“Basketball Wives” star Jennifer Williams is filing a lawsuit Wednesday accusing a Manhattan woman of a flagrant foul for viciously slapping her face during a taping of the reality show.

Williams, ex-wife of NBA player Eric Williams, also has filed a complaint with the state attorney’s office in Florida, said lawyer Sanford Rubenstein.

“Violence used against any person is wrong but when a woman hits another woman it sets a horrible example for young girls everywhere,” Williams told the Daily News.

“I choose to use the justice system to fight back,” she said in an exclusive interview.

The defendant, Nia Crooks, is a personal assistant to “Basketball Wives” co-star Evelyn Lozada. Crooks belted Williams while VH1 cameras were rolling Jan. 21 in the presidential suite of the Gulfstream Park racetrack in South Florida.
